To aZZ whom it may concern.-

Be it known that I, GEORGE POOLE, of Thompsonville, town of Enfield, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Stop-Motion Mechanism for Looms, of which the following is a specification.

This invention has relation generally to looms for weaving plush andother similar pile fabrics, and more particularly to the stopping mechanisms therefor, having for its object to provide certain improvements there in whereby the loom may be stopped manually or automatically to meet certain conditions and requirements.

The invention consists in a 100m possessing certain features of construction and relative arrangement of parts, all as fully illustrated upon the drawings now to be described in detail and finally pointed out in the claims hereunto appended.

Reference is to be had to the accompanying drawings, and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, Wherever they occur.

Of the drawings, Figure 1 represents in side elevation, partially in section, a portion of a loom embodying my invention. Fig. 2 represents a front elevation of the same, parts being broken away. Fig. 3 represents a section taken through the slide or bunter. Fig. 4 represents a perspective view of the connections between the various stopping mechanisms.

Referring to the said drawings,the standard a, the lay b, the swords b, the take-up c, and the magazine 01 are all of the ordinary construction. The lay carries the usual dagger 12 which in case of a mispick is allowed to drop and engage a shoulder b on the slide or bunter b on the support 12 The rear end of the bunter bears against a block b of rubber, which cushions it to prevent jarring of the loom.

Extending across the front of the loom is a rock-shaft f, encircled by a spring f, which normally holds it yieldingly against movement. Secured to the end of this shaft farthest from the magazine is an upright arm f terminating in a handle f and provided projectingvdownwardly into an eye h, swiveled in the end of one of the arms of a twoarmed lever H, secured upon a vertical rockshaft W. The arm h of said lever is arranged perpendicularly to said arm g and carries said eye, while the other arm h is pivoted to a connecting-rod 71 having its free end slotted, as at 71. to receive a stud b projecting laterally from the bunter or slide 11 There is a head on the stud If, as shown in Fig. 4, to

prevent its being disengaged from the slotted end of the connecting-rod h By this arrangement it will be seen that the rocking of the shaft f or the actuation of the bunterb will cause the vertical shaft 77/2 to rock also. Secured 'to said shaft 77, is an arm or latch '5, the hook or stop t" of which is adapted to engage the shipper-leverj, which is fulcrumed at j. This lever is provided with a pivoted handle j, having a finger j adapted to move past the edge of the reduced portion 7' thereof, the parts being so arranged that when the shipper-lever is swung in the direction of the arrow in Fig. 4 to start the loom the hook t" engages the edge of the said reduced portion j. In order, therefore, to disengage the lever from the hook, the handle j is pushed rearwardly and its finger 7' engages the end of said hook and thrusts it out of engagement with the said lever, the usual spring forcing the shipper-lever into position to disengage the clutch members on the power-shaft and stop the loom. The loom may also be stopped manually by means of the handles f or g, one at each side of the loom, so as to be quickly grasped by the operative in whatever position he may be with relation to the loom. The said handles f g are drawn forward to rock the shipper-shaft f, which in turn swings the stud g rearwardly, thereby rocking the shaft 71. and throwing the hook out of engagement with the shipper-lever.

The warp stopmotion (not shown) may be likewise connected with the devices previously described, whereby it will be seen that in case of a mispick, the failure or breakage of a fillingthread, or the breakage of a warp-thread the loom will be automatically stopped.

This is a division of my copending application, Serial No. 692,478, filed October 3, 1898.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made'or all of the modes of its use, I declare that what I claimis- 1. In a loom, the combination of a rockshaft, a filling stop-motion adapted to rock said shaft, a second rock-shaft transverse to the first-mentioned shaft, and operatively connected thereto, a latch connected to said second shaft, and a shipper-lever adapted to be held in operative position by said latch.

2. In a loom, the combination of a shipperlever, a latch for said lever, a rock-shaft on which said latch is mounted, a second rockshaft, a filling-stop-motion mechanism arranged to rock the last-mentioned shaft,mech- 'anism actuated by reason of the failure of a shuttle to reach its box, connections between the last-mentioned mechanism and the said first rock-shaft, and connections between said second rock-shaft and said first rock-shaft.

In a loom, the combination ofashipperlever, a rock-shaft having a latch to engage said lever, and also having an arm, a crossshaft provided with an arm engaging the firstmentioned arm to rock the rock-shaft and disengage the latch from the shipper-lever, and a handle on said cross-shaft.

4c. In a loom, the combination ofa shipperlever, a rock-shaft having a latch to engage said lever, and also having an arm, a crossshaft provided with a two-armed lever, one arm engaging said arm, and the other constituting a handle, and a spring for holding said latch in engagement with said shipperlever.

In testimony whereof I have aflixed my signature in presence of two witnesses.

GEORGE POOLE.
